Glass laminated articles and layered articles

Abstract

Laminated articles and layered articles, for example, low alkali glass laminated articles and layered articles useful for, for example, electrochromic devices are described.

What is claimed is: 
     
         1 . An article comprising:
 a glass layer having a coefficient of thermal expansion 50×10 −7 /° C. or less;   a functional material disposed on the glass layer;   a substrate comprising a glass, a polymer, or a combination thereof, and having a thickness greater than that of the glass layer; and   a laminate layer disposed between the substrate and either the glass layer or functional material.   
     
     
         2 . The article of  claim 1 , wherein the functional layer is selected from the group consisting of:
 an electrochromic,   a thermochromic,   a photochromic,   a low-e type,   an actively defrosting,   a transparent conductive oxide material,   or a combination thereof disposed on the glass layer.   
     
     
         3 . The article of  claim 2 , wherein the functional layer comprises an electrochromic material disposed on the glass layer and
 a protective layer disposed on a surface of the electrochromic material, which is not in contact with the glass layer.   
     
     
         4 . The article of  claim 1 , wherein the glass layer further comprises:
 an alkali oxide content of 10 percent by weight or less.   
     
     
         5 . The method of  claim 1 , wherein the alkali oxide content is 5 percent by weight or less. 
     
     
         6 . The article of  claim 1 , wherein the alkali oxide is sodium oxide. 
     
     
         7 . The article of  claim 1 , wherein the glass layer comprises a thickness of 2.5 mm or less. 
     
     
         8 . The article of  claim 1 , wherein the substrate further comprises: a soda lime glass having a thickness greater than that of the glass layer. 
     
     
         9 . The article of  claim 1 , wherein the substrate comprises an annealed, heat strengthened, or fully tempered soda lime glass. 
     
     
         10 . The article of  claim 1 , wherein the substrate is about 6 mm thick. 
     
     
         11 . The article of  claim 1 , wherein the substrate is less than 6 mm thick. 
     
     
         12 . The article of  claim 1 , wherein the laminate layer is disposed between the substrate and the glass layer. 
     
     
         13 . The article of  claim 1 , wherein the coefficient of thermal expansion is from 20×10 −7 /C to 50×10 −7 /° C. 
     
     
         14 . The article of  claim 1 , wherein the coefficient of thermal expansion is from 20×10 −7 /C to 35×10 −7 /° C. 
     
     
         15 . The article of  claim 1 , wherein the laminate layer further comprising a material selected from polyvinyl butyral, a UV curable resin, a thermoplastic, a thermoplastic ionoplast, polycarbonate, polyurethane, a UV curable polymer, silicone, and combinations thereof disposed between the substrate and either the glass layer or functional material. 
     
     
         16 . The article of  claim 1 , further comprising: an automobile window or an architectural window.
